Following migration to TestComplete 14.61 and Firefox 81, pages and objects are no longer recognized

[ChristopheC]

Hello everyone,

I have a problem because on my automatic test development machine, I was with TesComplete 14.60 and Firefox 77 and everything worked perfectly.

Having updated TestComplete to version 14.61, I saw that it supports Firefox version 81 (https://support.smartbear.com/downloads/testcomplete/firefox-patches/).
I didn't check that TestComplete was still compatible with Firefox 77 and I updated Firefox to version 81.

Result, pages and objects are no longer recognized 😪.

On the same machine, TestComplete 14.61 is still compatible with Chrome 80 🤔

I rechecked the Firefox settings (https://support.smartbear.com/testcomplete/docs/app-testing/web/general/preparing-browsers/firefox.h...) and everything is okay.

Where can the problem come from ?

I tried to reinstall Firefox 77 but that doesn't work anymore either.

thank you for your help

"C:\Program Files (x86)\SmartBear\TestComplete 14\x64\Bin\Extensions\tcFF81Hook.dll" is present.

Contains of tcFFHook.xml (x64) in attached file.

That page is telling you that TC 14.61 needs a patch installed to work with Firefox 81.  Did you install the appropriate patch after you upgraded to TC 14.61?

Thank you @Marsha_R for this answer.

At the time of writing this post, there was no patch available (Download Links column containing "The products support Firefox 81 out-of-the-box. No patches needed.").

I updated with the patch (TestComplete > Help > Check for Updates).

I saw that the tcFFHook.xml file has been updated to integrate Firefox version 81.0.1.7578

I've updated Firefox again because I'm on manual update.

Reboot computer.

Result always the same problem (see attached file).

There is a patch here.  I suggest trying that.

@Marsha_R,

I did the update (see my previous post).
I still have the problem in TestComplete 14.61.294.7.

I did see your post, thanks.  I'm suggesting you try that Firefox patch from that link and see if it changes anything. 

Otherwise here's the link for contacting Support

Hi,

I opened a support ticket and what solved my problem was to create a system environment variable MOZ_DISABLE_CONTENT_SANDBOX with value 1.

Hoping that it will help other people.

Good test.
